America's Worst Disasters: Fire, Flood, Plague, and Catastrophe

The fires, floods, hurricanes, epidemics, and failures that marked American history — and the reforms they forced.

Disasters have punctuated American history and, again and again, changed it. Cities burned, rivers drowned whole towns, plagues killed hundreds of thousands, and the failures of modern technology exposed the dangers of a complex nation. Each catastrophe is a story of loss — but also of the reforms, the rescues, and the resolve that followed. This guide gathers the worst of them.

It groups them by kind: the great fires and earthquakes, the storms and floods, the epidemics, the industrial and technological failures, and the deliberate catastrophes of terrorism. Each entry links to a full account.

Overview

Start here for the larger story - how catastrophe, natural and man-made, has tested American cities and reshaped the rules meant to keep people safe. The sections that follow group the disasters by kind.

Fire and Earthquake

Some disasters arrive in an instant. These entries cover the great fires and earthquakes that leveled American cities and forced the country to rebuild - and to rethink how it builds.

Plague

Disease has killed on a scale that rivals any war. These entries cover the epidemics that swept the country, overwhelming its hospitals and reshaping daily life.

Technological Catastrophe

Some disasters are the price of progress. These entries cover the failures of modern technology - the accidents and meltdowns in which the systems Americans relied on turned against them.

Acts of Terror

The deadliest disasters of the modern era were deliberate. These entries cover the attacks that killed Americans on their own soil and reshaped the country's sense of security.

Several of these disasters reshaped the nation in ways traced elsewhere — the Dust Bowl in the Great Depression, and the safety failures that drove the labor reforms of the era.
